Some key features of correction pens: - The liquid is thick and opaque, so it completely covers the text underneath. Most formulas are white, so they stand out on the paper. - The pens have a fine tip or nib to allow for precise application of the correction fluid. - They are quick-drying, so the correction fluid dries after use and does not smear. - Some pens have additional features such as a built-in eraser or correction strips to allow for minor corrections. - The correction fluid can be overwritten after it dries to make new corrections or edits to the text.
